RVA Automatic JII Leveling System Operating Instructions

1 RVA RVA RVA RVA JACKS Automatic JII Leveling System Operating Instructions RVA Company / 2005 RVA Company All Rights Reserved Pages 1 of 11 IMPORTANT: ALWAYS VISUALLY CHECK TO ENSURE JACKS UP BEFORE MOVING OR DRIVING THE COACH System OVERVIEW Your jack System is microprocessor operated with features built-in to handle many different Leveling problems. The System consists of the jacks with mounting brackets, a control console, wiring harness, motor pump, level module, dash mounted controls (on some models), bong (warning) alarm, and a valve complex with manual retract provisions.

2 Automatic Leveling 1. Motor home should be in parking gear during operation of the Leveling System . Ignition key should be in ignition position, although some coaches were configured from the factory to operate with the key in the accessory position. 2. Turn on the switch labeled POWER on the control console. One of the red lights located on or under the dash will also go on when the POWER switch is activated. All lights on the control console should flash on for at least of a second (except the WARNING JACKS DOWN light). The initial powering on of the control console performs a self-diagnostics test.

3 If either of the green lights is on, the System will remain inoperative, indicating a short in the System or a malfunctioning control console. If powering on produces no lights, check for burnt fuses. A fuse for the control console is located at the lower end of the box at the bottom. To gain access to this fuse, remove the one inch perforated plastic cap. The fuse is located on the printed circuit board inside this opening. Remove the fuse with a small screwdriver and replace with an AGA 15 fuse, NO LARGER. Another fuse or circuit breaker is also located under the dash.

4 See wiring diagram. RVA RVA RVA RVA JACKS Automatic JII Leveling System Operating Instructions RVA Company / 2005 RVA Company All Rights Reserved Pages 2 of 11 Once the System is powered on, one or two yellow lights may be illuminated. Whichever yellow light or lights are on, indicate that particular jack or jacks need to be lowered in order to obtain a level condition. If no yellow lights are on after initial power up, your coach is level. 3. Press rocker switch labeled Automatic Leveling and release. The top green light will start blinking and after a second delay the motor pump will come on and all the jacks will start extending downward.

5 The System will attempt to do a complete level in one operation. The coach is level when all yellow lights go out and the top green light stops blinking and goes out. If Leveling is not accomplished on the first all jacks plant down phase, the System will attempt to level four more times at seven second intervals. Note: If the battery is weak and is wired to power both the Automatic Leveling System motor pump and the control console, during the Automatic Leveling phase either green light may stay on and the System will become inoperative. If this occurs, cycle the main POWER switch off and on and attempt Automatic Leveling again.

6 If the above re-occurs, check the battery voltage. It should not drop below 9 volts during Automatic operation. If the battery is good and the System continues to be inoperative, one of the following things can be done: a) Install larger capacity battery b) Install heavier gauge battery cable to the motor pump c) Power the control console from a separate battery from the one used for the motor pump. Motor pumps can operate down to 6 volts. The control console is designed become inoperative at approximately 8 volts. 4. As the jacks extend downward the WARNING JACKS DOWN red light and the other dash mounted red light will start blinking and a bong alarm will begin sounding.

7 This alarm will also come on if the control console is off but the jacks are down when the ignition key is turned on. 5. During Automatic Leveling phase, if both green lights start flashing alternately, this is an indication that you have either reached maximum physical extension on one or more of the jacks or have reached maximum pressure for Automatic operation. After the Automatic Leveling phase has ceased, if one or more of the yellow lights are on, press the manual extend switch for the appropriate jack. This action by-passes the Automatic pressure switch limit and allows an increased pressure to be applied to the jack.

8 If the yellow light is still on, a block could be placed under one of the jack pads to get additional height or find another place to attempt Leveling . If a block is placed under a jack, only one jack should be blocked at any time. If blocking the jack pad of one of he rear jacks is necessary and the coach is on a slope, the opposite set of rear RVA RVA RVA RVA JACKS Automatic JII Leveling System Operating Instructions RVA Company / 2005 RVA Company All Rights Reserved Pages 3 of 11 wheels must first be blocked to prevent rolling. If anyone is going to change a tire or go under the motor home, the chassis frame must first be supported with appropriately rated jack stands.

9 *DO NOT ATTEMPT TO CHANGE TIRES OR GO UNDER THE MOTORHOME WITH RVA JACKS EXTENDED 6. The motor home will be level when the top green light stops blinking and all the yellow lights are out. If desired the ALL JACKS RETRACT or MANUAL mode can be done instantly at any time during any operation. However, this will override and cancel the Automatic operation. To re-initiate the Automatic operation, press the Automatic switch. 7. When Leveling is complete, turn off switch labeled POWER on the control console. Turn off the ignition key. ALL JACKS RETRACT ( Automatic RETRACT) 1.

10 Turn on switch labeled POWER on the control console. 2. Press rocker switch labeled ALL JACKS RETRACT and release. The bottom green light will start blinking and all jacks will start retracting. This operation has a four minute timer after which the bottom green light will stop blinking and go out. NOTE: On coaches prior to 2000, the ALL JACKS RETRACT switch has a built in redundancy feature that allows you to retract the jacks when the POWER switch is off. If there is power to the control console (ignition key is on and all fuses related to the Automatic are good), simply press and hold the ALL JACKS RETRACT switch and the jacks will retract as long as you hold the switch down.
